Moffett Towers II — Utility Precision on a Landmark Campus

Moffett Towers II

Results

  • Avoided costly PG&E delays by engaging early in both transmission and distribution coordination
  • Expedited PG&E plan approvals thanks to PSD’s utility designs and established agency relationships
  • Integrated temporary and permanent infrastructure, saving time and construction costs
  • Reduced permit comments and change orders with clear and accurate joint trench plans
  • Optimized system capacity planning, aligning PG&E load projections with phased tenant delivery

Solution

  • PSD was engaged early to lead all electric and gas utility planning, starting with load projection modeling and system capacity conversations with PG&E. The team: Provided master dry utility design for the entire campus
  • Created phased utility routing strategies to align with off-site improvements
  • Coordinated across PG&E’s Transmission and Distribution divisions
  • Integrated Rules 13, 15, 16, and 20 requirements into the planning
  • Delivered joint trench composite layouts and dry utility intents early to support city submittals
  • Facilitated early easement discussions with the client, PG&E, and City of Sunnyvale
  • Secured timely construction power infrastructure aligned with permanent utilities
  • PSD’s early involvement and technical depth positioned the project for execution clarity, saving the client both time and money.

Challenge

With multiple 8-story buildings, structured parking, and a central amenities hub, Moffett Towers II posed a series of complex infrastructure challenges:

  • PG&E system planning was unclear and fragmented, causing delays and risk to tenant delivery schedules
  • The project required extensive coordination with PG&E Transmission & Distribution, AT&T, and the City of Sunnyvale
  • High stakes: Schedule delays could jeopardize major tenant deliveries and increase holding costs
  • Off-site overhead relocation and on-site infrastructure needed to be phased and aligned with vertical construction timelines
